Fantasia

This may be an easy find, but I've been through all the files and folder I could find and think of (including the Github downloads), and I couldn't find anywhere how to change the interval of how a sound file plays. I can change the audio file, but not how often it plays. Mightn't anyone offer some advice on where that info might be found? Basically, I'm trying to change how often the 'chop' sound plays, so the animation and audio are in sync. Thought it would be an easy change, but I've discovered otherwise
